Never found a motive? Are you joking? We've got tons of info on the psycho who did it. He was a distraught aging white male with a history of depression, gambling, and firearms who wanted to hurt the world and kill himself.
Sad losers are a dime a dozen but at least most of them aren't as stupid as that guy. There is no reason to discuss this outside of proposed changes to our society as a whole to better prevent these stains on history.
I don't mean to sweep this under the rug, but I think that just stands as another case for the fact that an enormous amount of people in this country have mental health issues. It's normalized at this point.
Besides that, news outlets that report on this only do so basically of the drama and the views. The solutions are in front of us, always have been, but that's not what anyone truly cares about.
I mean you can discuss it to death, but without facts -- which don't exist, because he didn't tell anyone the intimate workings of his fucked up mind -- the best you can do is speculate. By all means, go ahead.
But but but why did he spray bullets at a crowd with intent to murder hundreds? Why, man, why? We need his manifesto, his tax records, the political affiliations of his associates and family! How else am I supposed to fit him into my narrative if I can't prove why he thought to do the unthinkable?
